IAmazonSQS.PurgeQueue (string)

Method

Deletes the messages in a queue specified by the queue URL.
When you use the PurgeQueue API, the deleted messages in
the queue cannot be retrieved.

When you purge a queue, the message deletion process takes up to 60 seconds. All messages
sent to the queue before calling PurgeQueue will be deleted; messages
sent to the queue while it is being purged may be deleted. While the queue is being
purged, messages sent to the queue before PurgeQueue was called may be
received, but will be deleted within the next minute.
